This function gets the radius of an element. Normally, sphere or circle-shaped elements tend to return a more accurate and expected radius than others with another shapes.

Syntax

float getElementRadius ( element theElement )

OOP Syntax Help! I don't understand this!

Method: element:getRadius(...)
Variable: .radius

Required Arguments

Returns

Example

This example shows how to get and output the radius of every player who types the /getmyradius command (which will always be 1).

    outputChatBox("Your radius is " .. getElementRadius(localPlayer))
end
addCommandHandler("getmyradius", outputLocalPlayerRadius)
